a_{r,c}

Here r is the row number and c is the column number.

Given matrix is:

A = \left[\begin{array}{ccc}3&6&9\\2&4&8\end{array}\right]

The elements of matrix will be represented by a_{r,c}

We have to find a_{1,3}

Which means that the first row and third column.

The first row is: 3   6    9 and the element in third column is: 9

So,

a_{1,3} = 9
